将相同的域名解析为不同的IP地址，比如我的DNS服务器（chinaskills.com）上有一个对应外网（100.100.100.100）和一个对应内网(192.168.100.100)的接口，而当外网用户想知道www.chinaskills.com这个主机地址时，取得是竟然是我对内的地址，那么还需要通过NAT才能连接到我内网的接口，为了提高解析速度和控制来着客户端的请求，可以通过view功能将我的区域设为不同的IP地址进行解析，内网的响应由我内网的zone，外网响应外网的zone。

（1）环境

关闭SELinux，关闭防火墙，时间同步

（2）WEB服务配置

[root@wwwserver ~]# yum -y install httpd

[root@wwwserver ~]# echo I am WWWSERVER > /var/www/html/index.html

[root@wwwserver ~]# curl 127.0.0.1

I am WWWSERVER

（3）开启路由转发

[root@dnsserver ~]# echo net.ipv4.ip_forward = 1 > /etc/sysctl.conf [root@dnsserver ~]# sysctl -pnet.ipv4.ip_forward = 1

（4）DNS服务器主配置文件

[root@dnsserver named]# cat /etc/named.conf

options {

listen-on port 53 { any; };

listen-on-v6 port 53 { ::1; };

directory "/var/named";

dump-file "/var/named/data/cache_dump.db";

statistics-file "/var/named/data/named_stats.txt";

memstatistics-file "/var/named/data/named_mem_stats.txt";

allow-query { any; };

recursion yes;

dnssec-enable yes;

dnssec-validation yes;

/* Path to ISC DLV key */

bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";

pid-file "/run/named/named.pid";

session-keyfile "/run/named/session.key";

};

logging {

channel default_debug {

file "data/named.run";

severity dynamic;

};

};

acl neiwang { 192.168.100.0/24; };

acl waiwang { !192.168.100.0/24; any; };

view "lan" {

match-clients { "neiwang"; };

recursion yes;

zone "." IN {

type hint;

file "named.ca";

};

include "/etc/lan.zone";

};

view "wan" {

match-clients { "waiwang"; };

recursion yes;

zone "." IN {

type hint;

file "named.ca";

};

include "/etc/wan.zone";

};

#include "/etc/named.rfc1912.zones";

include "/etc/named.root.key";

（5）区域文件配置

[root@dnsserver ~]# cd /etc/

[root@dnsserver etc]# cp -a named.rfc1912.zones lan.zone

[root@dnsserver etc]# cp -a named.rfc1912.zones wan.zone

[root@dnsserver named]# cat /etc/lan.zone

zone "chinaskills.com" IN {

type master;

file "lan1.zone";

allow-update { none; };

};

zone "100.168.192.in-addr.arpa" IN {

type master;

file "lan2.zone";

allow-update { none; };

};

[root@dnsserver named]# cat /etc/wan.zone

zone "chinaskills.com" IN {

type master;

file "wan1.zone";

allow-update { none; };

};

zone "100.100.100.in-addr.arpa" IN {

type master;

file "wan2.zone";

allow-update { none; };

};

（6）区域数据库文件配置

[root@dnsserver etc]# cd /var/named/

[root@dnsserver named]# cp -a named.localhost lan1.zone

[root@dnsserver named]# cp -a named.localhost wan1.zone

[root@dnsserver named]# cp -a named.loopback lan2.zone

[root@dnsserver named]# cp -a named.loopback wan2.zone

lan1.zone

lan2.zone

wan1.zone

wan2.zone
